Calculate the difference quotient for f(x) = 5 - x at a = 4. (Express numbers in exact form. Use symbolic notation and fractions where needed.) f(x)-f(4) x-4 f(x)-f(4) X-4 x-4 (Give an exact answer. Use symbolic notation and fractions where needed.) Calculate f'(4) by finding lim - f'(4) = Find an equation of the tangent line to f(x) at a = 4. (Express numbers in exact form. Use symbolic notation and fractions where needed. Let f(x) = y and express equation in terms of x and y.) Question Source: Rogawski 4e Calculus Early Transcendentals | Publisher: Wa
